Method Summary

Modifier and Type	Method and Description
static <T> SingleConverter<T,Completable>	flatMapCompletable(Function<? super T,? extends CompletableSource> onSuccessHandler, Function<? super Throwable,? extends CompletableSource> onErrorHandler) Maps the terminal signals of the upstream into CompletableSources and subscribes to it, relaying its terminal events to the downstream.
static <T,R> SingleConverter<T,Flowable<R>>	flatMapFlowable(Function<? super T,? extends Publisher<? extends R>> onSuccessHandler, Function<? super Throwable,? extends Publisher<? extends R>> onErrorHandler) Maps the terminal signals of the upstream into Publishers and subscribes to it, relaying its terminal events to the downstream.
static <T,R> SingleConverter<T,Maybe<R>>	flatMapMaybe(Function<? super T,? extends MaybeSource<? extends R>> onSuccessHandler, Function<? super Throwable,? extends MaybeSource<? extends R>> onErrorHandler) Maps the terminal signals of the upstream into MaybeSources and subscribes to it, relaying its terminal events to the downstream.
static <T,R> SingleConverter<T,Observable<R>>	flatMapObservable(Function<? super T,? extends ObservableSource<? extends R>> onSuccessHandler, Function<? super Throwable,? extends ObservableSource<? extends R>> onErrorHandler) Maps the terminal signals of the upstream into ObservableSources and subscribes to it, relaying its terminal events to the downstream.

Method Detail

flatMapCompletable

public static <T> SingleConverter<T,Completable> flatMapCompletable(Function<? super T,? extends CompletableSource> onSuccessHandler,
                                                                    Function<? super Throwable,? extends CompletableSource> onErrorHandler)

Maps the terminal signals of the upstream into CompletableSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a CompletableSource to continue with.

onErrorHandler - called when the upstream fails and should return the CompletableSource for the given Throwable instance to continue with.

Returns:

the new SingleConverter instance

Since:

0.20.2

flatMapMaybe

public static <T,R> SingleConverter<T,Maybe<R>> flatMapMaybe(Function<? super T,? extends MaybeSource<? extends R>> onSuccessHandler,
                                                             Function<? super Throwable,? extends MaybeSource<? extends R>> onErrorHandler)

Maps the terminal signals of the upstream into MaybeSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

R - the element type of the mapped-in MaybeSource

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a MaybeSource to continue with.

onErrorHandler - called when the upstream fails and should return the MaybeSource for the given Throwable instance to continue with.

Returns:

the new SingleConverter instance

Since:

0.20.2

flatMapObservable

public static <T,R> SingleConverter<T,Observable<R>> flatMapObservable(Function<? super T,? extends ObservableSource<? extends R>> onSuccessHandler,
                                                                       Function<? super Throwable,? extends ObservableSource<? extends R>> onErrorHandler)

Maps the terminal signals of the upstream into ObservableSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

R - the element type of the mapped-in ObservableSource

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a ObservableSource to continue with.

onErrorHandler - called when the upstream fails and should return the ObservableSource for the given Throwable instance to continue with.

Returns:

the new SingleConverter instance

Since:

0.20.2

flatMapFlowable

public static <T,R> SingleConverter<T,Flowable<R>> flatMapFlowable(Function<? super T,? extends Publisher<? extends R>> onSuccessHandler,
                                                                   Function<? super Throwable,? extends Publisher<? extends R>> onErrorHandler)

Maps the terminal signals of the upstream into Publishers and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

R - the element type of the mapped-in Publisher

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a Publisher to continue with.

onErrorHandler - called when the upstream fails and should return the Publisher for the given Throwable instance to continue with.

Returns:

the new SingleConverter instance
